Virgil Dupras 6beb082e29 acia: make wholly cross compilable 2020-05-11 21:52:44 -04:00
Virgil Dupras da371451cc Replace INITIAL_SP with PS_ADDR conf 
Now I struggle to remember why I ever did things they way I did.
There must have been a reason...
 2020-05-11 21:08:24 -04:00
Virgil Dupras 73482e7ea1 Reword root block 
Usage of "LIST" wasn't explicit enough for a complete newcomer. I
hope that with this wording, anyone can figure out how to navigate
blocks and learn the system.
 2020-05-11 20:12:21 -04:00
Virgil Dupras 73b6d9905e Add 7x7 font 2020-05-10 21:37:23 -04:00
Virgil Dupras 62ae1012df ti84: allow case select during a-lock with 2nd mode 2020-05-10 11:39:10 -04:00
Virgil Dupras a6aba40327 ti84: fix a-lock debouncing bug 
Yup, it was a deja vu. I remember now.
 2020-05-10 11:26:58 -04:00
Virgil Dupras 06a4674317 ti84: implement a-lock 
There's a bug where the first char after a-lock isn't a-modded. I
have troubles figuring it out for now. It feels like deja vu. I
think I had the same problem with asm.
 2020-05-10 09:37:36 -04:00
Virgil Dupras a476773813 Add words BIT@ and BIT! 2020-05-10 08:40:49 -04:00

Virgil Dupras 4ce0727c72 ti84: kbd driver wip 2020-05-09 11:55:58 -04:00
Virgil Dupras 2f1e635b9d ti84: tidy up driver code 
Pushed all words directly interfacing with ports and memory offsets to
low level layers. This saves us the need for keeping those variables in
runtime memory.
 2020-05-09 08:50:55 -04:00
Virgil Dupras b2d71cb1ee ti84: add Z offset mechanism 2020-05-09 08:13:49 -04:00
Virgil Dupras afc2327770 Split icore in 2 parts 
The goal is to insert device drivers in between.
 2020-05-08 21:47:03 -04:00
Virgil Dupras baf725aa38 Move a bunch of words from core to inner core 
That makes it easier to write drivers that can be xcompiled.
 2020-05-08 20:55:50 -04:00
Virgil Dupras ffdc58739a ti84: HelloWorld! 
In emulator of course...
 2020-05-08 11:36:50 -04:00
Virgil Dupras b90efb0f7f ti84: first glyph on screen! 
On the emulator of course...
 2020-05-08 09:07:44 -04:00
Virgil Dupras 58ec54fc97 ti84: wip 
Gave more priority to CPU in the emulator because initialization would
otherwise be horrendously slow.

Virgil Dupras 114e753b64 ti84: WIP 2020-05-08 06:50:34 -04:00
Virgil Dupras 24e588019b Add words RSHIFT and LSHIFT 2020-05-07 15:41:43 -04:00
Virgil Dupras 4e98ef11bd ti-84+: wip 
I need RSHIFT and LSHIFT first...

Virgil Dupras 690d9e6313 editor: improve I 
Make it print edited line and also have it adjust cursor pos.
 2020-05-06 17:41:49 -04:00
Virgil Dupras 58ece9f9a1 editor: implement I command 
Also, made LIST properly handle full 64-chars lines not ending with
a null or CR. Previously, such a line would be accompanied by its
following line, duplicating that line's output.
 2020-05-06 12:19:36 -04:00
Virgil Dupras f54b1dc504 Add 2>R and 2R> 
This allows us to make DO..LOOP more compact.

Virgil Dupras 60b4bbf28a Fix DUMP's broken "round up to next 8" logic 
This was caused by the removal of signed-ness a long while ago.

Virgil Dupras 9df053b76c z80a: add CPn, 2020-05-05 21:49:26 -04:00
Virgil Dupras fa79e3d8a6 Make (print) stop on CR 
Lines edited with the Block editor end with 0xd and (print) spits
spurious CR when printing those lines.

Also, properly initialize ACC in BROWSE.
 2020-05-05 15:49:50 -04:00

Virgil Dupras 8ef197d248 Make linker more compact 
There was a weird empty block in the middle of the program.
 2020-05-03 20:33:36 -04:00
Virgil Dupras a96b5f1dec Restore DOES> section in usage guide 
I removed it because it was redundant with Starting Forth, but
I directly reference it in the dictionary, so well...

Virgil Dupras f023f9bcb4 Pack core words blks a bit tighter 
With all this recent movements, we had a bit of a fragmentation
issue.

Virgil Dupras 3d908cef3a Move all parsing words to Inner core 
This allows us to get rid of the (parse*) indirection.

Virgil Dupras 931c812394 Remove cmp 
Not worth the complexity and space.

Virgil Dupras 2a578b3352 editor: implement F 2020-05-01 21:52:38 -04:00
Virgil Dupras ecca70c7f3 Add layer of indirection to EMIT 
This would allow things like temporary giving control to the *CL
line on the TRS-80. For example... A very far fetched example. Not
at all the only *raison d'etre* of the layer...
 2020-05-01 20:05:15 -04:00
Virgil Dupras 5bf3baff05 editor: add edit buffer

Virgil Dupras 0044011f06 Move AT28 and TRS80 drivers to higher blocknos 
I'm reserving the 100-200 range for non-bootstrapping needs.
 2020-04-29 21:04:10 -04:00
Virgil Dupras 0cf26547ff Add words FLUSH and COPY 2020-04-29 20:21:18 -04:00
Virgil Dupras 1b2c4b519e icore: add BIN+ 
This allows us to write LATEST at proper offset in emul/stage1.fs in
cases where we set a nonzero BIN(.
 2020-04-29 11:42:09 -04:00
Virgil Dupras fc67b88720 Make BIN( offsetted binaries closer to working at all 
I have a working offset-by-0x100 stage0 now.
 2020-04-28 21:12:52 -04:00
Virgil Dupras 0b8c8c9ca0 recipes/trs80: still wip... 2020-04-28 10:12:16 -04:00
Virgil Dupras 61b2e02351 xcomp: remove XOFF and use ORG and BIN( instead 2020-04-28 09:37:00 -04:00
Virgil Dupras 838548843e boot: apply BIN( to stray stable ABI references 
With cross compiling and IMMEDIATE words, things get icky with stable
ABI references. For the same reason that EXIT, (br) and (br?) need to
stay at stable offsets, these word references will not have BIN(
properly applied at Inner core xcomp.

The solution for now is to adjust during EXECUTE, which is ugly and
inefficient, but I don't see a better solution right now.
 2020-04-28 08:52:47 -04:00
Virgil Dupras 4501313410 Add [IF] .. [THEN] 
Will be useful as kinds of "#ifdef"s during xcomp.

 2020-04-27 18:11:54 -04:00
Virgil Dupras 295b4b6e0a z80a: add BIN( parameter 
Will be useful for assembling binaries for the TRS-80 which can't start
at addr 0.
 2020-04-27 15:11:38 -04:00
Virgil Dupras 865f4f9256 Move AT28 driver to blkfs

Virgil Dupras a2f164ecc3 emul: bootstrap to stage2 from within Collapse OS! 
Big bootstrapping change which greatly reduces the role of the modern
operating system in the bootstrapping process.
 2020-04-26 10:24:09 -04:00
Virgil Dupras 0e3cf7fa02 Add word ," 2020-04-26 09:01:49 -04:00

Virgil Dupras 13771d8c92 xcomp: add XPACK 2020-04-25 16:02:47 -04:00
Virgil Dupras 389b23fe1a Change C<? mechanic 
It's now a simple flag updated by the C< implementation. No more
routine pointer.

The goal is to avoid tons of "ok" during a LOAD operation.
 2020-04-25 09:10:25 -04:00
Virgil Dupras 5219887ad7 sdc: implement _crc16 in z80 2020-04-24 20:46:01 -04:00
Virgil Dupras 8d78ca9dac tests: add test_sdc 
The SD card driver is a bit too slow to be bearable. I'll write
_crc16 in z80 and see how it goes.
 2020-04-24 18:23:29 -04:00
Virgil Dupras 816563e2e3 Stop LOADing on ABORT 
This is done by adding a "C<* override" layer that is reset to 0 on
ABORT.

The problem was that when ABORT happened during a LOAD, we had a
resetted RSP and started from a clean INTERPRET, but LOAD didn't
have the opportunity to restore C<*, which caused it to continue
interpreting from the faulty BLK.

With a C<* override, we don't need to *restore* C<*, we just need to
clear the override.
 2020-04-24 14:10:40 -04:00
Virgil Dupras af39b37dd1 Replace the "> " prompt with the more traditional "ok" one 
This is more than cosmetic, it's also highly usable. The presence
or absence of the "ok" message allows us to know whether the command
aborted. Previously, the "> " prompt appeared when the system expected
a prompt in the INTERPRET context, whether the previous command aborted
or not.

Also, this allows us to get rid of that ugly FLAGS global variable.
 2020-04-24 12:10:07 -04:00
Virgil Dupras 44403c3d4c Move icore to blkfs 
The way is clear for complete stage1 bootstrapping on the RC2014
target!

Virgil Dupras 8fbbf5209a Copy sdc driver to blkfs 2020-04-23 13:55:00 -04:00
Virgil Dupras a19376df6c Copy ACIA driver to blkfs 
We can get rid of acia.z80, but not of acia.fs yet, we still need it.
 2020-04-23 12:42:41 -04:00

Virgil Dupras 338769a0a8 z80a: add PUSH0, PUSH1, PUSHZ, macros 2020-04-22 19:03:32 -04:00
Virgil Dupras 7a0e63746f parse: don't validate 0x and 0b lengths 
It doesn't serve much purpose and takes up many precious bytes. And,
after all, parsed didn't do it either...
 2020-04-21 20:40:23 -04:00
Virgil Dupras 372524fd19 Move xcomp to blocks 2020-04-21 20:30:14 -04:00

Virgil Dupras 58c017448f z80a: add JPccnn, 2020-04-20 21:18:33 -04:00
Virgil Dupras d466c6d95d emul: make stage2 load z80a from blkfs 
This allows us to remove forth/z80a.fs. Another big step towards
self-hosting!
 2020-04-19 21:31:41 -04:00
Virgil Dupras 0892193cbe Copy z80a.fs to disk blocks 
I don't remove z80a.fs yet because build process needs it, but that
will change shortly.
